Initial lighting
The boiler is supplied as standard for use with Natural Gas and tested at an operating
pressure of 20 mbar. The boiler must not be put into operation with a different type of
gas without reference to Broag.
The boiler is delivered with a restriction that is suited for H-gas (Ø H gas = 8.6 mm).
If the boiler is connected to L- gas, a different restriction (Ø L gas = 9.8 mm) must be
placed between the gas valve multiblock and the venturi.
